Five9 Sponsors Aberdeen Report

PLEASANTON, Calif. (September 11, 2007) - Five9, Inc., the leader in on-demand call center solutions, today announced its has sponsored a recently released report titled "Contact Center on Demand: Right Price . Right Results" from Aberdeen, a Harte-Hanks Company (NYSE: HHS). The benchmark report details how Best-in-Class (BIC) call centers see optimizing their service delivery model as a way to reduce up-front technology costs. By utilizing a hosted model such as the Five9 Virtual Call Center™, 65% of the BIC respondents have experienced benefits from flexible on-demand licensing and an increase in available functionality.

"I cannot stress enough the importance of measuring KPIs," said Alan Hubbard, SVP Customer Management Technologies Group at Aberdeen. "Our research has shown time and time again that on average laggard companies don't measure KPIs about 80-90% of the time. If a company doesn't measure its performance it has no idea what technologies are most needed and when they are needed. At the very least, its business operations run inefficiently, clearly not an indicator of Best-in-Class business."

Key findings of the new report include:

58% of BIC firms plan to use predictive dialing in the next two years, an increase from 29% today;

79% of respondents see optimizing their service delivery models as a way to reduce up-front technology costs; and,

65% of respondents saw benefits from flexible on-demand licensing and an increase in available functionality.

"Five9 is excited to support Aberdeen's leading market research as it benefits so many decision makers in the call center industry," said Brian Silverman, CEO if Five9. "This was a great opportunity for Five9 to be involved in a project that educates call centers and enterprises around the world on industry trends and the trials and successes of their colleagues and competitors."
